Abstract (en)
[origin: EP3629538A1] An embodiment of this application provides a communications method. The method includes: receiving, by a serving device from a terminal, a first terminal identifier associated with an anchor device, where the first terminal identifier is used to identify the terminal and the anchor device; sending, by the serving device, a wireless configuration parameter and the first terminal identifier to the anchor device; receiving, by the serving device from the anchor device, the wireless configuration parameter encrypted by using a first key, where the first key is a key used by the terminal to communicate with the anchor device; and sending, by the serving device to the terminal, the wireless configuration parameter encrypted by using the first key. The anchor device encrypts, by using the first key used by the terminal to communicate with the anchor device, the wireless configuration parameter allocated by the serving device to the terminal, thereby improving security of communication between the serving device and the terminal and reducing signaling overheads for performing key negotiation over an air interface.
